Frequently Asked Questions

  • Q1. What is backflow testing for?

    Backflow testing evaluates the backflow prevention system if it is working properly or not. The backflow system works to stop the water to flow backward and enter the clean water supply. Backflow testing ensures that the water backflow prevention system is working properly.

  • Q2. Is backflow testing necessary?

    Yes, backflow testing is a necessary part of the water backflow prevention process. As per state and local municipal laws, it is compulsory to get annual water backflow testing as it helps to keep the water supply safe and clean for citizens.

  • Q3. How is backflow testing done?

    The backflow testing procedure involves two basic steps; first, checking if water backflow is present or not, and second, finding a cause and fix it. In the test procedure, gate valve and relief valve are used with backflow testing device. The tester closes the valves and checks the differential gauge movement and water leakage.

  • Q4. What is the purpose of backflow testing?

    Drinking water usually flows in one direction from source to tap, but because of pressure change or other mechanical problems, sometimes, water starts flowing in opposite direction and it is called water backflow. Water backflow contaminates the drinking water and becomes the reason for many water-borne diseases. The backflow testing helps to find the problem that is causing this water backflow and fix it.

  • Q5. What is an RPZ test?

    RPZ is a type of backflow prevention device that ensures safe water flow and prevents water backflow.
